Application filed August, 2, 1 926 Seria1 Ne.f126,515. Renewed January 24, 1928.

The invention relates to a sash fastener,

as described in the present specification and illustrated in the accompanying drawings that form part of the same. i

The invention consists essentially of the novel featuresof construction pointed out broadly and specifically in the claims for novelty following a description containing an explanation in detail of an acceptable form of the invention.

The objects of the invention are to furnish a fastener whereby the upper and lower sashes of a window may be opened at convenient distances and held; to supply a fastening that will enable the upper sash of the window to be opened at a required distance and fastened, thereby insuring ventilation within a room and at the same time preventing any undesirable intrusion therethrough; to construct a fastener that will be easily applied to any sash of a window frame and that will be easy to operate; .and generally to provide a device that'will rigidly lock sashes of a. window frame in either closed or open positions, and which will be cheap to manufacture, durable in construction and efficient for its purpose.

In the drawings, Figure 1 is a'perspective view of a window frame showing upper and lower sashes and having. the deviceapplied thereto and showing the upper and lower sashes in their locked position.

Figure 2 is a perspective view of the window frame showing upper and lower sashes having a modified form of the fastening device. t

Figure 3 is an enlarged perspective detail of the device.

Figure 4 is an enlarged perspective detail of a modified form of the invention.

Figure 5 is an enlarged detail of the single locking device. 2

Like numerals of reference indicate corresponding parts in the various figures.

Referring to the drawings, the window frame has the upper and lower sashes 11 and 12 of the usual construction and the fastening device is adapted to be secured to'both' of these sashes and as shown in Figure 1. The fastening device is formed of the bracket 13 which is screwed to the lower sash by the screws 14 and 15 and has the suitably shaped side walls 16 and 17, each containing a bearing member 18 and. 19, while in the upper sash the angle bracket 20 is in the same position.

screwed the'reiniat 2 1, the angle 22 containing the key slot 23.

The rod 24 extends through the bracket 20 and is at its upper end connected to a plate 25 containing the key slot 26 and this plate 25 is adapted to overlap the angle 22 and having its key slot 26 corresponding with the key slot 23, through which the nut 27 and bolt 28 are adapted to be inserted, thereby 'securely fastening the rod 24 to the bracket of the upper sash.

Encircling this rod is a fastening" lever 29 which is suitably shaped in athumb lug 30 and having its sides atone end forming rod'bearing members 31 and 32, these meme bers being suitably shaped to engage with the bracket 13 of the lower sash and cushioned within this bracket through thewashers 33 and 34'on either side of the fastening lever which encircle the. aforementioned rod. This rod 'is'suitably' shapedat its lower end to form a lifting member through" which the upper sash is adapted to be lowered or raised to its proper hei ht. It will thus be seen that wien it is desired to raise the upper sash to its full length the rod is lifted upwardly and when the upper sash is extended as far as it will go,

the clamping lever is then swung inwardly, Y

which will have the effect of making the aforementioned members engage with the raised or' loweredtogether and at the same time be looked, a very important feature in this invention.

It may also be convenient as an extra safeguard to have two clamping levers in a window, so that if by any chance one of the clamping levers is forced open then the other clamping lever will still keep the sashes What I claim is V o 1. A sash fastener comprising. a rod bracket formed of an angle bracket having a key slot extending into the twosections, a rod and rod holes therethrough for the sliding of said rod, a clamping member mounted on the rod and having a binding lug on the one side engaging the said base plate and a handle for operating and springs'cushionifig said clamping member above and below saicl binding lug.
